The short answer is yes — a principal investigator (PI) may have to leave academia if they experience a lapse in funding. The impact of losing funding often depends on the PI’s employment structure. Some PIs hold hard money positions, meaning their salary is supported by stable, institutional sources like a university’s operating budget, which provides more job security.
Others hold soft money positions, where salary and sometimes even access to research space, depends largely or entirely on external grants, making their role more vulnerable to funding gaps.
That said, there are strategies to reduce this risk. Some PIs have access to non-federal funding sources—such as philanthropic gifts or industry contracts—which can sometimes be set aside as an emergency reserve. Institutions may also offer bridge funding—short-term support to help PIs maintain research operations while they apply for new grants. This may be awarded through a competitive process or on a case-by-case basis.
Some institutions and research fields also offer funded professorships or endowed chairs, which provide guaranteed financial support for salary and, in some cases, research expenses, regardless of external grant status. These roles can offer greater long-term stability.
To further minimize funding gaps, PIs often diversify their funding sources across agencies and research areas and carefully time their grant applications to stagger award periods. In some cases, PIs can request to extend unspent funds beyond a grant’s end date—especially if progress was delayed by unforeseen events.
These strategies don’t eliminate all risk, but they can significantly increase the chances of sustaining a research career through uncertain funding periods.
